I really did a number on my three wheeler fellas. First I changed the final drive oil and let it drain for a couple days into a butter container. I went out and checked it,looked like oil, only was a solid block of ice. Must have been mostly water,maybe an ounce of oil, the rest frozen. Put fresh oil in and backed out of my barn in 18 inches of power snow and got stuck hard in only 10 feet out. Put it from Reverse to low back and forth and then it started grinding in the rear end and then no drive in any gear,it just revs up like its in neutrel, but the wheels are locked when the trans is in neutrel. Did I destroy the rearend? What do I need to take apart first/check first? thanks for any help and love this site!;)
